ICE CREAM CARTON Filed March 25, 1964 2 Sheets-Sheet 2 IN VENTOR F/P/rz PE/ZP Zj MW United States Patent M 3,197,115 ICE CREAM CARTON Fritz Peter, Shrewsbury, Mass., assignor to West Virginia Pulp and Paper Company, New York, N.Y., a corporation of Delaware Filed Mar, 23, 1964, Ser. No. 353,967 2 Claims. (Cl. 229-51) My invention relates to an improved carton for packaging ice cream or similar products. The carbon is constructed from a two piece blank. My invention provides a more economical carton construction, which is lightweight, easily assembled and easy to open. Most prior art cartons however, are made from a one piece blank. This prior art construction necessitated a complicated arrangement of panels to provide for opening. The carton of my invention is easily made on a die-cut press from suitable sheet material. Construction of the carton blank permits a very significant increase in the number of blanks that may be struck from a suitable piece of sheet material. This results in a decreased cost per blank. The improved arrangement called nesting is made practical by the use of a second blank to form the carton walls. The use of a two piece blank results in problems of joining the pieces to form a suitable carton that is leakproof, and suitable for graphic printing. The carton of my invention provides a solution to the problems. The ice cream carton of my design uses less sheet material and lighter sheet material, is easier to manufacture, easier to open, and is leak-proof for liquids. No joints are displayed on outside panels which provides a better display of graphic printing.

The container is assembled from integral bottom and top panels and a separate portion forming front and side wall panel sections. The front and side Wall panels are rectangular in shape and thus there is no waste of sheet material when the panel is struck from a suitable blank. The bottom-top panels portions are also struck from a rectangular blank reducing the loss of sheet material.

The carton may be constructed as follows by referring to the accompanying drawings and descriptions. FIG- URE 1 illustrates the blanks from which the carton may be constructed. FIGURE 2 illustrates an assembled carton in a partly closed condition. FIGURE 3 illustrates a completely assembled and constructed carton. FIG- URE 4 illustrates a carton which has been opened and also illustrates the tear strip structure.

FIGURE 1 illustrates a blank from which the bottom and top panel section of the carton may be assembled. The blank is scored and cut to form a bottom panel 19 having fold lines 20, 21 and 22, a tab 23 and a tab 24 connected to the bottom panel along fold lines 20 and 21 respectively, a back panel 10 having fold lines 11, 12, 13 and 14, a pair of tabs 15 and 16 foldably attached to the back panel along lines 11 and 13 respectively. The tabs have chamfered ends 17 and 18, top panel 26 having fold lines 27, 28 and 29; the panel is foldably con- 'nccted to the back panel along fold line 12. A front panel 36 is connected to the top panel 26 along fold line 28. The front panel hasedges 31, 32, and 33. Spaced lines of weakened resistance form a pull tab 34 in a portion of front panel 30. The pull tab 34 has an elongated area 35. A pair of side panels 36 and 38 are attached to top panel 26 along fold lines 27 and 29 respectively. Side panels 36 and 38 have lines of weakened resistance forming pull tabs 37 and 39 respectively. The portions of the side panels at an edge remote from the fold lines 27 and 29 are designated as portions 46 and 47 respectively. Side panel 36 has a front tab panel 49 foldably attached along fold line 28. The tear strip extends into front tab 3,197,115 Patented July 27, 1965 panel 49 and has elongated portion 55, similarly panel 38 has front tab panel 4-1 with tear strip 39 extending into the front tab panel and having an elongated portion 43. The cut lines forming edges 31 and 33 separate the front panel from the front tab panels. Another blank 60 is cut and scored to form wall panels having a pair of side walls 61 and 65 and front wall 63 foldably connected at fold lines 62 and 64 respectively.

Front wall 63 is attached along its bottom edge 67 to tab 25, side wall 65 is attached along its bottom edge 69 to tab 23, side wall 61 is attached along its bottom edge 68 to tab 24, edge 70 of side wall 65 is attached to tab 15 and edge 71 of side wall 61 is attached to tab 16 when the carton is assembled.

When the carton is formed and sealed the panel sections 42, 46 and 47 are sealed to front Wall 63, side Wall 61 and side wall 65 respectively.

FIGURE 2 illustrates a carton in a partly closed condition. Front tab panel 41 is folded along fold line 23 into the surface of front panel 30, similarly front tab panel 49 is folded into front panel 30. The elongated portions 55 and 43 respectively of tear strips 37 and 39 are adhered to pull tab 34. The closure section thus having a continuous pull tab extending throughout the side and front panels. When tab 0 is pulled tear strip 39 is disengaged from panel 38, the action is transmitted to tab 35, thence to tab 55; and tear strips 34, 37, 39 are thus disengaged from their respective panel portions. The closure portion may be thrown back as illustrated in FIG- URE 4, providing access to the contents. Tabs 15, 16, 23, 24 and 25 are folded upwardly, panel sections 42, 46 and 47 are fastened to the tabs, providing a seamless, smooth, exterior surface for the package.

The relationship of the tabs to the wall portion provides a relatively wide area of contact for the application of fastening compounds. This wide area of contact considerably reduces the chance of seepage of the contents, provides a rigid and strong carton assembly. The cartons are designed for assembly by automatic equipment. The relatively simple steps required for assembly facilitate the machine handling.

The closure portion with incorporated tear strip opening avoids the problem of complicated fold-back arrangement of panels usual in the prior art cartons.

The sheet material used in the construction of the carton may be of different densities due to the two piece construction. The difference in density of the wall portions and body closure portions permits the use of different Weight board, less costly board, thereby producing a saving in material costs.

An area of side panels 3-6 and 38 and front panel 30 is adhered to the side walls and front wall in the portion marked 46, 47 and 42 respectively. When the carton is in opened condition a portion of the panels remains adhered to the wall panels as shown in FIGURE 4. The carton is closable merely by returning the top portion over the walls.

Having thus described my invention, what is claimed is:

1. A blank for an ice cream carton or the like comprising:

(a) a back panel,

(b) a pair of tabs foldably connected along opposite sides of the back panel,

(c) a bottom panel foldably connected to the back panel along another side thereof,

(d) a pair of tabs each foldably connected to the bottom panel along opposite sides thereof,

(e) a tab foldably attached to the bottom panel along another side thereof,

(f) a top panel foldably connected to the back panel,

(gla pair of side panels foldably connected to the top panel along opposite sides thereof,

(h) a front tab panel foldably connected to eachside panel,

(i) a front panel foldably connected along another side of the top panel, the front tab panels being secured to a surface of the front panel when a carton is formed from the blank, 7

(j) the front panel having a tear strip dividing a portion of the front panel,

(k) each of the side panels having a tear strip dividing (m) the tear strip of each side panel being aligned with the tear strip of its respective front panel. 2. The carton blank of claim 1 wherein the separate Wall panel is made of a sheet material which is substan- 5 tially less dense per square inch of area than the sheet material of the other panels.
